* fix(auth): land stock email-change links on the status page and stop retries voiding pending mails

A secure email change needs one click in each mailbox. Stock GoTrue links
verify on the GoTrue host and return to /auth/callback through redirect_to
with ?message= (first click), ?error= (dead link) or ?code= (completing
click); none carries a token_hash, so the callback bounced every one of
them to /login with no message. Users read that as a failure and pressed
"Byt" again, and because the claims fast path carries no new_email, the
route re-issued both tokens on every press and voided the links they were
about to click.

- /api/account/email stamps flow=email_change on emailRedirectTo and reads
  pending state from GoTrue when the session claims lack it, so a repeat
  request inside the 30-minute window is a no-op instead of a re-send.
- /auth/callback routes flow=email_change redirects to
  /auth/email-change?status=partial|done|failed; hook-style token_hash
  links keep using the existing verifyOtp branch.

* fix(auth): let signed-in stock email-change redirects through the proxy and treat a minted code as done

Skeptic findings on e5639fb43:

- The proxy bounced authenticated /auth/callback requests to / unless they
  carried type=email_change. Stock GoTrue links return with only the
  flow=email_change marker, so the new status branch was unreachable from
  the signed-in browser the change usually starts in. Exempt the marker too.
- A completing click opened in a browser without the PKCE verifier (phone
  mail app) failed the code exchange and, with no session to inspect, was
  reported as a failed change although GoTrue had already flipped the
  address. A code is only minted after that verify, so report done.

* fix(auth): gate email-change requests with an atomic per-user claim

CodeRabbit on PR #2199: the pending-state read from GoTrue is not atomic,
so two concurrent POST /api/account/email calls (two tabs, a retried
fetch) could both see nothing pending and both re-issue the confirmation
tokens, voiding each other's mails.

Migration 20260903083000 adds email_change_requests (one row per auth
user, RLS with no policies) and two SECURITY DEFINER RPCs:
claim_email_change_request(p_email, p_window_seconds) is a single
INSERT ... ON CONFLICT DO UPDATE whose row lock serialises concurrent
claimers, so exactly one caller per address per window wins; a different
address always wins; release_email_change_request drops the claim when
GoTrue refuses the change so the user can retry.

The route claims right before updateUser, answers resent:false when the
claim is held, releases on GoTrue failure, and falls through to GoTrue if
the RPC itself errors. pg-real test covers sequential, windowed,
concurrent, per-user, release and RLS behaviour. Applied to staging with
the same version.

MattssonandClaude Fable 5 341d61131a fix(auth): email-change recovery re-send and confirmation feedback (#2034)
* fix(auth): email-change recovery re-send and confirmation feedback

A half-completed secure email change was a dead end: the pending-address
short-circuit in /api/account/email swallowed every retry without
re-sending mails, so once the confirmation links expired the user could
never recover, and confirmation clicks landed on the dashboard with no
feedback at all.

- /api/account/email: only short-circuit a repeat request while the
  pending mails are fresh (30 min); a stale pending change falls through
  to GoTrue, which restarts the change and re-sends both mails
- /auth/callback: type=email_change now redirects to a status page
  (/auth/email-change) that says whether one click remains, the change
  is complete, or the link was dead, instead of landing silently
- auth mail templates: both email-change mails explain that two mails
  are sent and both links must be clicked
- settings: the save button re-enables for the pending address as
  Skicka igen, so users can trigger the re-send themselves

* fix(auth): exempt email-change confirmations from the authenticated /auth bounce (skeptic findings)

- middleware: let /auth/email-change and /auth/callback?type=email_change
  through for authenticated users; the bounce to / swallowed confirmation
  clicks before verifyOtp ran (pre-existing since #2017)
- email-change done page resolves the WL-14 landing destination for the CTA
- /api/account/email returns resent flag; settings toast says mails were
  already sent instead of claiming a fresh send

MattssonandClaude Fable 5 7f0f25b558 feat(account): self-service login email change with double confirmation (#2017)
* feat(account): self-service login email change with double confirmation

New POST /api/account/email requests the change via the user session so
Supabase's AAL2 guard applies, and the account settings page gets an email
row with pending-confirmation state. Confirmation mails (both addresses)
and the /auth/callback email_change verification already existed; this
wires the missing initiation.

* feat(account): map email_exists to a 409 with Swedish copy

Changing to an address that already has an account is refused by GoTrue
(addresses are unique per auth user); surface that as a clear conflict
instead of the generic fallback.

* fix(account): trusted redirect origin + profiles.email sync trigger (skeptic findings)

- emailRedirectTo now derives from resolveRequestAppOrigin(): request.url
  can be an internal origin behind a proxy (dead confirmation links on
  self-hosted) and auth links must not follow attacker-chosen hosts;
  registered white-label hosts keep their brand.
- New migration 20260828191950: sync_profile_email trigger mirrors
  auth.users.email changes into profiles.email (member lists, notification
  recipients, AGI/KU contact, invite dedup all read profiles.email), plus a
  backfill for already-diverged rows. pg-real test included.
- Save button disabled while the same address awaits confirmation (no
  rate-limit re-fires); GoTrue's 'error sending email change email' now maps
  to the Swedish SMTP guidance.

* fix(account): idempotent repeat request for the pending address

CodeRabbit follow-up: a second POST for the address already awaiting
confirmation now returns the pending state without another GoTrue round
trip (no duplicate confirmation mails, no rate-limit burn). Claims-mapped
sessions lack new_email; GoTrue's send rate limit remains the backstop.
